fix compilation error when building against old libkqueue

dgrove-oss · dgrove-oss · commit 43c0659f2d7b · 2016-07-21T08:34:32.000-04:00
Should have used an ifdef instead of an if to guard this block
of code.  Fixes compilation on linux when using an older version
of libkqueue that doesn't include the nsec kevent support.
